Abstract
A device may include an electronic display having a backlight that generates light and multiple display pixels that modulate the amount of generated light emitted from the electronic display based on compensated image data. The backlight may include multiple illuminators that generate the light, and a first color component illuminator may have a slower response rate than a second color component illuminator. The device may also include image processing circuitry that generates the compensated image data by compensating input image data for a color shift associated with a change in brightness of the backlight and the slower response rate of the first color component illuminator. The input image data may be compensated by increasing first color component pixel values of the input image data relative to second color component pixel values of the input image data, and the compensated image data may be output to the electronic display.
